Patent EP-0087893-A1 (EP)
Inventor: COLE WILLIAM A
IPC: G01R19/04
Filed: 1983-02-18
Abstract: he detector includes a voltage-to-current converter (10) that generates a current signal (1 1 ) comprising a quiescent current and an alternating current signal which varies directly with an input alternating voltage signal (12). A current sink (14) absorbs the current signal (1 1 ) up to a controllable maximum current level (l 2 ). A charge current (1 3 ) is generated when the current signal exceeds the maximum current level (l 2 ), and is delivered to a capacitor (18). Feedback circuitry (22) varies the maximum current level of the current sink (14) directly with the resulting capacitor voltage. The capacitor voltage is consequently indicative of the peak magnitude of the alternating voltage signal. A discharge current is applied to the capacitor so that the capacitor voltage can decrease in response to a decrease in the peak magnitude of the alternating voltage signal.

Abstract: A servo control system for a data recording system having a radially movable optical system mounted on a fine tracking actuator (14) which is mounted on a coarse positioning actuator (18), which is in turn radially movable with respect to an optical recording media disk. The servo control system is coupled to receive optical system position signals derived from optically sensed tracking information on the optical recording media disk and position information derived from data information received from the optical recording media disk and further receives information from a position sensing system (23). The position sensing system, in operation, senses the relative position of the fine tracking actuator (14) with respect to the coarse positioning actuator (18). The servo control system, in operation, controls the movement of the fine tracking actuator (14) through a first servo control loop and the coarse positioning actuator through a second servo control loop to position the optical system at a desired position, and is operable simultaneously to position both the fine tracking actuator and the coarse positioning actuator by operating said first and second servo control loops in response to a difference between actual and desired positions of the optical system.
